UTILIZING HEAT ENERGY.

mama o ofAlameda and State of California, have invented certain new and useful Improve mentsin Utilizing Heat'Energy; and I do hereby declare the following to be a full, clear, andexact description of the same.

This invention relates to the art of process of utilizing the expansive. force of heat. It also involves improvements in dynamics as embodied in heat motors; pneumatics as in air compressors and other gas apparatus: hvdraulics as in pumps and other water devices.

In the devices and methods adoptedheretofore, in utilizing heat as a source of power, an exceedingly large proportion of the heat valueof fuels has becn'wastefully dissipated.

The present invention is a radical departure from the accepted practice having for i'ts'object the utilization of much of this heretofore wasted heat energy.

In general terms the/objects of the inven tion are to effect high initial and especially low terminal temperatures of an inflamed charge, and to transform this wide range into an equivalent of useful work. It aims "to utilize a larger percentage of the fuel heat .value, by providing conditions in harmony with the requirements for harnessing heat energy as displayed in explosive action.

5 Incidental to themain object of the invention and more fully stated, some of the objectsare to provide conditions in the utilization of-explosive energy to effect-high initial temperature and pressure; low terminal temperature and pressure; expansion below atmosphere; high piston speed; immediate conversion of the fugitive energy of. explos'ion into a stable form of practically available pressure; compression of charge prior to ignition; prior compression of charge in proportion to theresistance to be met by its expansion during infiaming; comj in position and operation this piston consists of a volumeof fiuid, prefe rably water. ,Means are also provided for changing or 1 regulating the position of the surface of i th s piston in chamber 1. In the present inpression automatically produced, regulated and controlled by the resistance to be overcome; expansion commensurate with varying initial temperatures and pressures; extreme mobility and responsiveness of piston to initial pressure; transmitting association between piston and power storing or utilizing means providing for the resistance being Specification Letters Patent.

or process is made. available in the arrange o ment of the simple means shown ,in the 'accompanymg drawings in which v D Figure 1 1s aside view of a single cylinder apparatus, largely in section to more clearly, illustrate it. v Fig. 2 is an elevation of a two 5 cylinder or duplex apparatus havinga common air chamber and charging mechanism. Fig. 3 is aseries of diagrams illustrating the cycle of operations or steps in the process as carried into'efl'ect in the apparatus shown in Fig.2. Fig. 4 is a series of diagrams illustrating varients of the single and multiple apparatus adapted to carry into effect the 1 herein disclosed artor process.

Referring to; the drawing, 1 is a cylinder (using this term conventionally) of any suitable form, which constitutes a charge, explosion or expansion chamber. This cylinder is prolonged into an easy curve 2, and

the curve 2 is tapered to a nozzle outlet 3'86 directed upward. The nozzle 3 projects intoand is surrounded by a casing or uptake t tapering in the opposite direction, from the nelghborhood of the nozzle, to form an injector on a large scale. At the lower end of casing 4 is placed a suitable check valve 5 and strainer 6,. and at theupper end of the casing'another check valve7. An air inlet valve. 5 is provided, opening into the ex plosion and expansion chamber or its extension.- The structure thus described from its commencement, around the curve to the valve 7 comprises the charge and expansion chamber. Above the check valve 7 is placed 7 an air-chamber 8. A pipe 9-connects the air chamber 8 with the casing 4 below the valve 7 A valve 10 is provided on the pipe 9 to control the flow of air or water from the chamber 8 into the casing 4. A'suitable independent freely movable pistonis located 0 in chamber 1. In the resent form of the device illustrated in Figs. 1 and 2, when stance as illustrated in Figs. '1' "and 2 it'is shown as piston 11, movable in a cylinderin communication with the chamber 1, so that 110.

The'rod 13 in is connec e .to a motor eylinder .15;;hy-..suitable connec- 3' the fluid piston, though entirely independent and free to move in res' onse' to heat pressure impulse,- is also on er control as to its position. Power connections are represented by a rock-shaft 12, with levers to operate iston 11 and thevarious valves for control- 'ng the charges and effecting the ignition.

As illustrated inFigJ'2 the piston '11 is provided with a rod 13 which extends through 'a stufling-box 14 in the'side of the tions such as -levers. 17, rock-shaft tratedm the'fbrm sie'ither Fig. 1 or Fig. 2. A pipe forms an outlet for the chamber 7 or chambers 8.61 Thee-chambers 8, if more than one, are conneetedhso-as to form one .air

chamber of large size compared with. the

ggf 'volume of the water-piston. In other words the iston should always be-of relatively sinal .sizeas compared with the resilient cushion of the air chamber. To operate in proper sequence the other working or con-. trolling devices, I" provide the followmgdev scribed mechanism. A cam lever and tap.-

pet 21 is attached securely on shaft 12 having cam surfaces 21 and 21". A plug valve 22 is common to and controls the flow of gases to or from the two explosion chambers. It is shown connected to the e lesion chamber in Fig. 1 by pipe 23. A chec valve 24 controlling the admission of the explosive charge, is provided-with a spring actu-T ated valve stem 25, as shown in Fig. 1. v

The operating lever or handle'22f is se+ cured to'the plug or stem ofth'e valve .22. A slotted 1ink22 is loosely connected to 22 and engages with, one arm of a loosely pivoted bell-crank tappet lever 22. The other arm of the lever 22 constitutes a tappet which engages with the part 21' ot the cam ended lever 21 to be operated thereby at eacl; arc reciprocation of the camend of the lever. This cam end serves the double function of reversing the four-way valve 22 and. raising and keeping the valve 24 open, by engagement of the cam surfaces 21 and 21" with the stem connections of valves 22 and 24 respectively. This is shown in Fig. 1. A vaporizer or fuel-mixer 26 is connected to a fuel reservoir 27 by a suitable valve con.-

An exhaust pipe for the four way valve 43 is shown at.46 which permits each end of cylinder 15 to exhaustalternately. .An'op-Z' crating lever 47 is provided furl-valve 43,

which is-connected to a sliding tappet rod- 48 having springs 49 and tappets 50. Levers 51, hinged-at one end and each provided, at

provided. The opposite end .of'each lever is provided with a wedge-shaped latch, to en-' with and release the latch levers '51 alternately. of which is clearly .shown in unit or single cylinder device. All the working parts are in operative association. Thus,

from this view, bein .partly in" section, the construction of the evice and the steps of the process will be clearlyv understood. The course of the explosive charge and the water can also clearly be followed from their sources to their outflow. In this view the main body of the explosion chamber '1 is shown entirely submerged, its small extension or ignition tube 23 alone appears above Water. In this view also, the charging cylinder is shown connected directly with the; explosion or combustion chamber 1. discharge pipe 20 leads from the air cham ber 8 near thebottom'thereof but sufiiciently above the valve 7 to provide a water seal thereto.

thu's'completingthe cycle.

In the foregoing brief description of the diagrams of Fig.3, emphasis has'not been 'laid--=on' the operation and function of valve 5 in the cycle and process, as the question ofits use is a matter, largely within the discretion andj'udgment of the operator and dependent on'the nature of the work to be done in relation to the head to which the water is to be forced. It should in pracqtically all cases be used to insure best economy. 'Its'u'se enables atmospheric pressure to be employed to displace the water in the air chamberto the level of the discharge opening and thereafter supply air absorbed by the water underpressurein the air chamher, and. in addition thereto,'it permits the excess of atmospheric pressure over that required to force water; into chamber 1 to be the lexpansion of the chargegases and th movement of, the water" employed in lighteningthe column and so reducin the resistance to be overcome-by theexp osive charge.

"With the foregoing mechanical construction 'of the apparatus andits cycle, its mechanical operation and the steps of'the process carried into efiect thereby, will be simple and apparent to those skilled in kindred arts. f A brief descri tion therefore will suifice, of the practicall operation o'f'the apparatus and how the process is carried into eflect thereby This will now be given. 'Motion is imparted'to the piston llby the operation of the small engine 15 ai1d by the described or othersuit ;able mechanism, the various valves and other moving parts are worked in proper sequenee; The action ofthe piston llcauses the flurd piston to move in the chamber'l and make roon 'for the charge in its cham her. The valve 22 being the action of piston 11 an water piston causes successive inflow of explosive charges and expulsion or scavenging of the spent gases. Assuming as is'shown in properly disposed,

Fig. 1, the explosive charge to be in chamber 1, the water piston will extend nearly to valve 7, separated from, the water and pressure inthe air chamber 8 by the valve 7 and 'by-wh'atever air has been permitted access water piston while free to respond to the explosive impulse,"is under control and mov-' able at will.v The charge in the combustion chamber 1 and the air chamber 8 are now under like pressure, which is as has been shown,:that due and corresponding to the head to which the liquid is being forced. It may he noticed also that the ignition chamber 29 with ltssparker is in free communication with the'explosion chamber. Ignition now takes place by the engagement of the tappet pm} 37 with the end oftheslot in the link 36 thus rocking the wiper 30 past the spring "33: by the connection of the link 36 to wiper arm 32. The slot in 36 permits the valvd 10 to close immediately the wiper arm 32 passes out of engagement with the spring 33. By the. explosive expansion of the'gases,

cylinder 1, the water piston is driven with great energy and speed through the nozzle 3. The entire water piston may be driven out'of the expansion chamberthrou h valve 7.- The size of the expansion cham or .is a

A. few such varients are diagrammatically illustrated in Fig; 4'. I

Of these, a brief; description will now be given.

j Diagram IX represents an apparatus substantiallysimilar 'tothat shown in Fig. 2,

but in-w-hichthe expansion chamber is so roportioned that e expansion extends yond valve 7 and 0 an extent commensurate to reducing the pressure of the expand+ inggas much below atmosphere. So that during the time that expansion pressure is .below atmosphere valve 5" is opened by atmospheric pressure. It admits air and atmospheric pressure into both the expansion chamber and. the air-chamber, behind the. water piston. The air beneath the iston andzabove the valve 7 is trapped withln the air'ch'amber by the closing-of the valve 7, when the energy of explosion has spent in compressing the air in the air chamber. This trapped'increment or surplusage of air finds its way! ulltfof the air chamber with the water, through the water discharge pipe.-

' The explosion chamber is supplied with a fresh volume of water or water piston through the foot valve .by gravity; The compression of the charge is effected as already described with reference to Fig. 2, through the medium of air or water by the pressure of the airchamber.

Dia'gram X shows a device similar to Diagram IX with. the variation of the omission of the inlet and outlet for water. It thus constitutes a doubleacting air com pressor'. In this variant, as it is notdesired to transfer water to a higher level, the inlet for water is of course unnecessary, the valve 5 may be closed, or, as shown in the diagram, omitted. The water piston is used'continuously bein transferred back from-the air chamber 't rough the ipe 9. The compressed air is carried ofl, f r use, through pipe 54:, from the upper part of the air chamber. 2 p

vDiagram XI shows-a single acting air compressor formed of one cylinder or mem-- ber of the device illustrated in the preceding diagrams and having a combined solid and fluid piston. In this form valve fi'may act' as an inlet for atmospheric" pressure uponkthe bottom or back of the free piston. The piston is permitted to return by gravityp The valve 5" admits air and allows the piston to fall, and thus provides. successive volumes of air to be driven into the air chamber. The compression of the charge is eifected by the pipe 9 transferring air from the air chamber beneath \alve 7 'air cushion at each end of theapparatus,.

w-h ieh compressed cushion formsalternately the next explosive charge at each end.

Diagram XIV shows a motor form of the apparatus in-which the water piston compresses air alternately on opposite sides of a. piston-suitably connected to a crank to,

produce rotary motion from its reciprocation. .The water piston is returned as in Diagram X through the pipe 9. 'The conn pression of the charge-is also eli'ected as in by the operation of the valves l010. In all these variants the charge forming,

Ioontrolling and igniting devices may substantially conform to th'ose'shown in Fig. 1.

*Some of the novel and useful eli'ects, functlons and results disclosed by thls invention atmospheric pressure, beneath a column of liquid, which exerts astatic pressure many times that of atmos' here. The introduction of aresilient fluid into 'a liquid column and the column subjected to explosive or other,

pressure beneath .the point of introduction.

As indicating the scope of this invention, it may be stated that the charging and motor cylinders are not, of necessity, intimately connected with the air chamber or explosion chamber. They may be located at considerable distance therefrom, as 'for example, on the surface, with the explosion chamber at the bottom of a shaft or well,

as illustrated in Fig. 1 by the breaks shown in the pipes.

The whole device may be located at a point distant from that at which the work is being utilized. The compressed air,

water or impulse may be carried by pipes to suitable devices at the bottom of a shaftor other. distant location.

The displacement of the spent gases by liquid piston or induction of fresh charges thereby, is not of the essence of the invention these functions may be performed in many other ways. One such is illustrated in Fig. 1.

The injector form of construction may not always bedesirable nor is it essential.

The U or curved shape of connect-ion between the cylinder and uptake is only one convenient form. The uptake may concentrically or otherwise surround the cylinder, or be entirely omitted as in Diagrams XII and XIII.

The means shown for controlling the fluid piston gravity of the Water piston has been used to charge and exhaust the gases, though the ,means shown have been found positive and reliable.

The work required of the engine 15 is r so insignificantthat, in many instances, it \Vlll be found advantageous to operate a number of explosion-chambers, with an-engine and valve mechanism common to all,

as shown in the various views in whichthe engine serves for two explosion chambers. In some instances where a source of small power is available in any of the ordinary forms, it may be used with economy to operate the c rging and valve admission in a plant of considerable proportions. A wind null or even hand-power maybe made pump large volumes or water rapidly.
